I guess every popular show has these, it's a tradition by now.

it was a weird mix of bitterness and sweetness going through these clips as they remind you of how intense the pace was in the show but also how happy the crew looked while delivering that A-star performance. You really get to see more endearing sides of the characters from the show and disassociate their character from what they really are. Especially the bully cast, you know the show made a point of making you have them.
